K-Type sensor readings in cloud with Arduino + ESP8266 [IoT]

 

esp8266-ftdi

The last few nights I am playing with an Esp8266 module that I had laying around for months and never connected it to my local wifi. Its one of the first modules, the ESP-01. The plan was to connect it to an Arduino mini pro or Arduino nano which has a K-Type temperature sensor attached to it. Then the readings of this sensor would be passed to ESP8266 through the serial pins (RX/TX) and send them to Thingspeak.com.

You can check my github repository for more. You will also find there an example with a TMP36 temperature sensor.
